AgilentHCPL-250L/050L/253L/053L
LVTTL/LVCMOS Compatible 3.3 V
Optocouplers (1 Mb/s)
Data Sheet
Features
• Low power consumption
• High speed: 1 Mb/s
• LVTTL/LVCMOS compatible
Description
These diode-transistor optocouplers
use an insulating layer between a
LED and an integrated
photodetector to provide electrical
insulation between input and
output. Separate connections for
the photodiode bias and output-
transistor collector increase the
speed up to a hundred times that of
a conventional phototransistor
coupler by reducing the base-
collector capacitance.
These optocouplers are available
in an 8-pin DIP and in an industry
standard SO-8 package. The
following is a cross reference
table listing the 8-pin DIP part
number and the electrically
equivalent SO-8 part number.
The SO-8 does not require
"through holes" in a PCB. This
package occupies approximately
one-third the footprint area of the
• Available in 8-pin DIP, SO-8
• Open collector output
• Guaranteed performance from
temperature: 0˚C to +70˚C
• Safety approval, UL, CSA, IEC/EN/DIN
EN 60747-5-2
Applications
• High voltage insulation
• Video signal isolation
• Power translator isolation in motor
drives
• Line receivers
